BACKGROUND

1. Field of the Disclosure

The present disclosure relates in general to wireless power transmission, and more specifically to a System Software for managing a wireless power transmission network.

2. Background Information

Electronic devices such as laptop computers, smartphones, portable gaming devices, tablets and so forth may require power for performing their intended functions. This may require having to charge electronic equipment at least once a day, or in high-demand electronic devices more than once a day. Such an activity may be tedious and may represent a burden to users. For example, a user may be required to carry chargers in case his electronic equipment is lacking power. In addition, users have to find available power sources to connect to. Lastly, users must plugin to a wall power socket or other power supply to be able to charge his or her electronic device.

An approach to mitigate this issue may include using RF waves through suitable power transmission techniques such as pocket-forming. This approach may provide wireless power transmission while eliminating the use of wires or pads for charging devices. In addition, electronic equipment may require less components as typical wall chargers may not be required. In some cases, even batteries may be eliminated as a device may fully be powered wirelessly.

The approach may enable the creation of wireless power networks similar in structure to regular wireless local area networks (WLAN) where a wireless access point is used to provide internet or intranet access to different devices. An access point or wireless transmitter may provide wireless power charging to different receiver devices.

Electric energy is an important and expensive resource. At times improper handling of electric energy may lead to waste of the valuable resource, in other cases too much electrical current may damage certain devices. It may also be beneficial in some cases to allow power sources to prioritize certain devices over others. Thus, a need exists for a system for managing power transmission in a wireless power network.

SUMMARY

Disclosed is a system and method for managing a wireless power network. The wireless power network may include wireless power transmitters with an embedded wireless power management application. The power transmitter manager application may include a device database where information about wireless power network may be stored such as, power receiver ID's, transmitter ID's, end-user handheld devices, system management servers, charging schedules and/or any relevant data to the wireless power network.

The wireless power network may include a plurality of client devices with wireless power receivers built in as part of the device or adapted externally. Wireless power receivers may include a power receiver application configured to communicate with the power transmitter manager application in a wireless power transmitter. Communication between wireless power transmitters and wireless power receivers may be achieved using standard network communication protocols such as, Bluetooth, Bluetooth Low Energy or WIFI.

The wireless power network may further include a wireless power manager application. The wireless power manager may be a software application hosted in a computing device. The wireless power manager application may communicate with a power transmitter manager application to extract and update information from the device database such as, statuses, power schedules, setting priorities, authentication credentials and the like. Wireless power manager may include a GUI which may be used by a user to perform management tasks.

DESCRIPTION OF THE DRAWINGS

Reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used here to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Alterations and further modifications of the inventive features illustrated here, and additional applications of the principles of the inventions as illustrated here, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.

FIG. 1 illustrates wireless power transmission 100 using pocket-forming. A transmitter 102 may transmit controlled Radio Frequency (RF) waves 104 which may converge in 3-d space. These RF waves may be controlled through phase and/or relative amplitude adjustments to form constructive and destructive interference patterns (pocket-forming). Pockets of energy 106 may form at constructive interference patterns and can be 3-dimensional in shape whereas null-spaces may be generated at destructive interference patterns. A receiver 108 may then utilize pockets of energy produced by pocket-forming for charging or powering an electronic device, for example a laptop computer 110 and thus effectively providing wireless power transmission 100. In some embodiments, there can be multiple transmitters 102 and/or multiple receivers 108 for powering various electronic devices, for example smartphones, tablets, music players, toys and others at the same time. In other embodiments, adaptive pocket-forming may be used to regulate power on electronic devices.

FIG. 2 illustrates a component level embodiment for a transmitter 202 which may be utilized to provide wireless power transmission 100 as described in FIG. 1. Transmitter 202 may include a housing 204 where at least two or more antenna elements 206, at least one RF integrated circuit (RFIC 208), at least one digital signal processor (DSP) or micro-controller 210, and one optional communications component 212 may be included. Housing 204 can be made of any suitable material which may allow for signal or wave transmission and/or reception, for example plastic or hard rubber. Antenna elements 206 may include suitable antenna types for operating in frequency bands such as 900 MHz, 2.5 GHz or 5.8 GHz as these frequency bands conform to Federal Communications Commission (FCC) regulations part 18 (Industrial, Scientific and Medical equipment). Antenna elements 206 may include vertical or horizontal polarization, right hand or left hand polarization, elliptical polarization, or other suitable polarizations as well as suitable polarization combinations. Suitable antenna types may include, for example, patch antennas with heights from about ⅛ inches to about 6 inch and widths from about ⅛ inches to about 6 inch. Other antenna elements 206 types can be used, for example meta-materials, dipole antennas among others. RFIC 208 may include a proprietary chip for adjusting phases and/or relative magnitudes of RF signals which may serve as inputs for antenna elements 206 for controlling pocket-forming. These RF signals may be produced using an external power supply 214 and a local oscillator chip (not shown) using a suitable piezoelectric material. Micro-controller 210 may then process information sent by a receiver through its own antenna elements for determining optimum times and locations for pocket-forming. In some embodiments, the foregoing may be achieved through communications component 212. Communications component 212 may be based on standard wireless communication protocols which may include Bluetooth, Bluetooth Low Energy, Wi-Fi or ZigBee. In addition, communications component 212 may be used to transfer other information such as an identifier for the device or user, battery level, location or other such information. Other communications component 212 may be possible which may include radar, infrared cameras or sound devices for sonic triangulation for determining the device's position.

Multiple transmitter 202 units may be placed together in the same area to deliver more power to individual power receivers or to power more receivers at the same time, said power receivers being within power reception range of all the power transmitters 202.

FIG. 3 illustrates a component level embodiment for a receiver 300 which can be used for powering or charging an electronic device as exemplified in wireless power transmission 100. Receiver 300 may include a housing 302 where at least one antenna element 304, one rectifier 306, one power converter 308 and an optional communications component 312 may be included. Housing 302 can be made of any suitable material which may allow for signal or wave transmission and/or reception, for example plastic or hard rubber. Housing 302 may be an external hardware that may be added to different electronic equipment, for example in the form of cases, or can be embedded within electronic equipment as well. Antenna element 304 may include suitable antenna types for operating in frequency bands similar to the bands described for transmitter 202 from FIG. 2. Antenna element 304 may include vertical or horizontal polarization, right hand or left hand polarization, elliptical polarization, or other suitable polarizations as well as suitable polarization combinations. Using multiple polarizations can be beneficial in devices where there may not be a preferred orientation during usage or whose orientation may vary continuously through time, for example a smartphone or portable gaming system. On the contrary, for devices with well-defined orientations, for example a two-handed video game controller, there might be a preferred polarization for antennas which may dictate a ratio for the number of antennas of a given polarization. Suitable antenna types may include patch antennas with heights from about ⅛ inches to about 6 inch and widths from about ⅛ inches to about 6 inch. Patch antennas may have the advantage that polarization may depend on connectivity, i.e. depending on which side the patch is fed, the polarization may change. This may further prove advantageous as a receiver, such as receiver 300, may dynamically modify its antenna polarization to optimize wireless power transmission. Rectifier 306 may include diodes or resistors, inductors or capacitors to rectify the alternating current (AC) voltage generated by antenna element 304 to direct current (DC) voltage. Rectifier 306 may be placed as close as is technically possible to antenna element 304 to minimize losses. After rectifying AC voltage, DC voltage may be regulated using power converter 308. Power converter 308 can be a DC-DC converter which may help provide a constant voltage output, regardless of input, to an electronic device, or as in this embodiment to a battery 314. Typical voltage outputs can be from about 5 volts to about 10 volts. Lastly, communications component 312, similar to that of transmitter 202 from FIG. 2, may be included in receiver 300 to communicate with a transmitter 202 or to other electronic equipment.
